If you fill up a glass and let it set for awhile does it clear up? Probably air.

If it does not clear up, see a clergyman.

Is this a recent happening or an ongoing issue? Is there a taste to the foam?

Our water comes out foamy but that's when first flushing out the antifreeze in the spring. Also, the foam tastes like the antifreeze. It takes running water through the lines for several minutes before it's flushed enough to not foam or taste weird.

There could be other issues, but I thought I'd throw this one out to you in case your situation is similar.


P.S. Noticed you also posted same ? in General Discussion forum. Consensus there seems to agree with antifreeze in line theory.

The foamy water is just air in the water. After I replace my whole house water filter I get foamy water until I run several gallons.

Sounds like the antifreeze was not completely purged from the lines. Even a small amount can cause the type of foaming you describe.

Not antifreeze. We sometimes have the problem and have never had antifreeze in the system.

I have to agree with Techie. After 37 years of changing water filters[I Was a Plumber before retirement] I have seen it more times than you can imagine. You either put new filters in or had dry filters for the winter storage. The foam will subside after the element is thoroughly saturated with water.

Your water heater is another source of foam. The design allows for a small cushion of air in the top of the tank. Normal en-route jostling causes the water to absorb the air, plus pressurized water slowly absorbs the air.
This is why some technicians recommend draining some water from your heater tank occasionally, to re-introduce the air pocket. The purpose of the air pocket is to allow for water expansion when heated. Ever read of someone's over-pressure/temp valve dripping?
If anyone knows different please link to the source.
